FIG. 1 illustrates an example wireless communication system 100 inaccordance with various aspects and embodiments of the subjectdisclosure. In one or more embodiments, system 100 can comprise one ormore user equipment UEs 104 and 102, which can have one or more antennapanels having vertical and horizontal elements. A UE 102 can be a mobiledevice such as a cellular phone, a smartphone, a tablet computer, awearable device, a virtual reality (VR) device, a heads-up display (HUD)device, a smart car, a machine-type communication (MTC) device, and thelike. UE 102 can also refer to any type of wireless device thatcommunicates with a radio network node in a cellular or mobilecommunication system. Examples of UE 102 are target device, device todevice (D2D) UE, machine type UE or UE capable of machine to machine(M2M) communication, PDA, Tablet, mobile terminals, smart phone, laptopembedded equipped (LEE), laptop mounted equipment (LME), USB donglesetc. User equipment UE 102 can also comprise IOT devices thatcommunicate wirelessly. In various embodiments, system 100 is orcomprises a wireless communication network serviced by one or morewireless communication network providers. In example embodiments, a UE102 can be communicatively coupled to the wireless communication networkvia a network node 106.

The non-limiting term network node (or radio network node) is usedherein to refer to any type of network node serving a UE 102 and UE 104and/or connected to other network node, network element, or anothernetwork node from which the UE 102 or 104 can receive a radio signal.Network nodes can also have multiple antennas for performing varioustransmission operations (e.g., MIMO operations). A network node can havea cabinet and other protected enclosures, an antenna mast, and actualantennas. Network nodes can serve several cells, also called sectors,depending on the configuration and type of antenna. Examples of networknodes (e.g., network node 106) can comprise but are not limited to:NodeB devices, base station (BS) devices, access point (AP) devices, andradio access network (RAN) devices. The network node 106 can alsocomprise multi-standard radio (MSR) radio node devices, including butnot limited to: an MSR BS, an eNode B, a network controller, a radionetwork controller (RNC), a base station controller (BSC), a relay, adonor node controlling relay, a base transceiver station (BTS), atransmission point, a transmission node, an RRU, an RRH, nodes indistributed antenna system (DAS), and the like. In 5G terminology, thenode 106 can be referred to as a gNodeB device.

Wireless communication system 100 can employ various cellulartechnologies and modulation schemes to facilitate wireless radiocommunications between devices (e.g., the UE 102 and 104 and the networknode 106). For example, system 100 can operate in accordance with aUMTS, long term evolution (LTE), high speed packet access (HSPA), codedivision multiple access (CDMA), time division multiple access (TDMA),frequency division multiple access (FDMA), multi-carrier code divisionmultiple access (MC-CDMA), single-carrier code division multiple access(SC-CDMA), single-carrier FDMA (SC-FDMA), OFDM, (DFT)-spread OFDM orSC-FDMA)), FBMC, ZT DFT-s-OFDM, GFDM, UFMC, UW DFT-Spread-OFDM, UW-OFDM,CP-OFDM, resource-block-filtered OFDM, and UFMC.

However, various features and functionalities of system 100 areparticularly described wherein the devices (e.g., the UEs 102 and 104and the network device 106) of system 100 are configured to communicatewireless signals using one or more multi carrier modulation schemes,wherein data symbols can be transmitted simultaneously over multiplefrequency subcarriers (e.g., OFDM, CP-OFDM, DFT-spread OFMD, UFMC, FMBC,etc.).

In various embodiments, system 100 can be configured to provide andemploy 5G wireless networking features and functionalities. 5G wirelesscommunication networks are expected to fulfill the demand ofexponentially increasing data traffic and to allow people and machinesto enjoy gigabit data rates with virtually zero latency. Compared to 4G,5G supports more diverse traffic scenarios. For example, in addition tothe various types of data communication between conventional UEs (e.g.,phones, smartphones, tablets, PCs, televisions, Internet enabledtelevisions, etc.) supported by 4G networks, 5G networks can be employedto support data communication between smart cars in association withdriverless car environments, as well as machine type communications(MTCs).

In an embodiment, UE 102 or 104 can determine when a beam failure of abeam pair link has occurred and determine whether to initiate a beamrecovery process based on the importance of the beam pair link, or basedon the amount of downlink control information or uplink controlinformation being passed by the beam pair link. Temporary interferencecause by blockage (due to the millimeter wave wavelengths of thetransmission medium) can render one or more beam pair links(transmission streams from an antenna on a transmitter to a antenna on areceiver) of MIMO transmission disabled. This can prevent the decodingof the blind decoding candidates in the transmission and requireretransmission. If only a small amount of downlink control informationis missing however, the transmission process can proceed, withoutretransmission of the missing downlink control information. Therefore,by taking into consideration the importance of the control resource set(the set of blind decoding candidates in the transmission carrying thedownlink control information) unnecessary beam recovery procedures canbe avoided.

Turning now to FIG. 2, illustrated is an example block diagram showing amessage sequence chart 200 in accordance with various aspects andembodiments of the subject disclosure.

In an embodiment, a gNodeB (or other network node) 202 can issue areference signal 206 that can be received by a UE 204. The referencesignal can be beamformed in some embodiments, or non beamformed in otherembodiments.

Based on the reference signal 106, the UE 104 can measure the channelresponse, and determine channel state information (CSI) to give asfeedback to the gNodeB 202. The channel state information can alsoprovide an indication of the reference signal quality at 208 and caninclude a channel quality indicator, precoding matrix index, or advancedPMI. This channel state information can refer to the known channelproperties of the communication link between the gNodeB 202 and the UE204. The channel properties can reflect how the signal propagates fromthe transmitter to the receiver and represents the combined effect of,for example, scattering, fading, and power decay with distance.

Based, on channel state information, the gNodeB 202 can then senddownlink control information (DCI) 210 to the UE 204 which enables theUE to receive data over a data traffic channel, or uplink controlinformation which can facilitate configuring the UE 204 to send databack to the gNodeB 202. The downlink link control information and/oruplink control information can be encoded in one or more radio resourceelements in a transmission. The physical resource elements cancorrespond to one subcarrier and/or one OFDM symbol. The UE 204 canperform blind decoding of a set of PDCCH candidates that may contain theDCI 110. The number of candidates blindly decoded can be based on thesearch space and/or aggregation level of the channel. In an embodiment,each beam pair link can transmit a control resource set (group of blinddecoding candidates). The control resource sets can have varying numbersof blind decoding candidates at different aggregation levels (the numberof physical spaces or radio resource elements that DCI information canbe mapped to). Higher aggregation levels mean that the same amount ofDCI is mapped to more locations, which increases the robustness of thetransmission.

The relative importance of the beam pair link can be determined at 212based on the control resource set the beam pair link is associated with.A control resource set is a set of resource elements where each UEattempts to blindly decode the downlink control information. A user canhave one or more control resource sets. Each control resource set can beassociated with a search space, and the search space can includeaggregation level(s) and number of decoding candidates for eachaggregation level.

In an embodiment, UE 204 can be configured with multiple controlresource sets. Each control resource set is associated with certainnumber of blind decoding candidates. (The number of blind decodingcandidates may be implicitly decided by the size of control resourcesets in terms of resource elements A resource element can be thesmallest modulation structure, or data unit. Each control resource setis associated with a set of beam pair links where each beam pair linkincludes a transmitter beam and a receiver beam. Each set of beam pairlinks is associated with a reference signal resource which is used toestimate the quality of the set of beam pair link.

In an embodiment, a beam failure event can be defined as “more than Neffective blind decoding candidates failed” and the value of N isconfigured by network depending on local conditions. When the referencesignal resource (maybe CSI-RS or SS-block) corresponding to a controlresource set failed, all the blind decoding candidates associated withthe control resource set are also considered to have failed. In someembodiments, a beam failure event can be based on the aggregation levelof the control resource set. For instance, a beam failure event can bedefined as “more than N effective blind decoding candidates with acertain aggregation level that have failed”.

After determining that the beam failure event has occurred, the UE 204can request a beam recovery at 214, and at 216, the gNodeb 202 caninitiate a new beam pair link using a different set of antennas.

As an example, UE 204 can be configured with 2 control resource sets (ofdownlink control information). Control resource set 1 associated with afirst beam pair link has 12 blind decoding candidates and controlresource set 2 has 2 blind decoding candidates. So, if the set of beampair links associated with control resource set 1 failed (according tothe measurement associated RS resource), the total number of failedblind decoding candidates is 12. If the reference signal associated withcontrol resource set 2 failed or is below a predetermined signalstrength or signal to noise ratio, the total number of failed blinddecoding candidates is 2. If the network has as a threshold of 4 blinddecoding candidates failed to declare a beam failure, then the failureof the first beam pair link would trigger the failure, but the failureof beam pair link 2 (associated with control resource set 2) would nottrigger the failure.

In an embodiment when considering the aggregation level. if UE 204 canbe configured with 2 control resource sets. Control resource set 1 has12 blind decoding candidates, where 6 of the blind decoding aggregatesare at aggregation level 2 and another 6 blind decoding candidates areat aggregation 4. While control resource set 2 has 2 blind decodingcandidates at aggregation 4. And the failed blind decoding candidate isconfigured as aggregation 4 only. So if control resource set 2 failed,then the total number of failed blind decoding candidate would be 2while if control resource set 1 failed, the total number of blinddecoding candidates would be 6 which would trigger a failure event.

Turning now to FIG. 3, illustrated is an example block diagram 300 of anew beam pair link from the same network node in accordance with variousaspects and embodiments of the subject disclosure.

In an embodiment, a beam pair link 308 between network node 306 and UE304 can be blocked by object 302 (in the shape of a person, but could beany object capable of attenuating a millimeter wave transmission betweenthe network node 306 and UE 304). After determining that the referencesignal associated with the beam pair link 308 is below a thresholdsignal quality (e.g., as measured by signal strength, signal tointerference plus noise ratio, etc.), and after determining that thecontrol resource set associated with the beam pair link 308 is of enoughsignificance or importance, or comprises a predetermined number of blinddecoding candidates at a certain aggregation level, the UE 304 candetermine that the beam pair link 308 has experienced a failure event,and will send a request for beam recovery to the network node 306. A newbeam pair link 310 can be formed to retransmit the downlink controlinformation.

Turning now to FIG. 4, illustrated is an example block diagram of a newbeam pair link from a different network node in accordance with variousaspects and embodiments of the subject disclosure.

In an embodiment, a beam pair link 408 between network node 406 and UE404 can be blocked by object 402 (in the shape of a person, but could beany object capable of attenuating a millimeter wave transmission betweenthe network node 406 and UE 404). After determining that the referencesignal associated with the beam pair link 408 is below a thresholdsignal quality (e.g., as measured by signal strength, signal tointerference plus noise ratio, etc.), and after determining that thecontrol resource set associated with the beam pair link 408 is of enoughsignificance or importance, or comprises a predetermined number of blinddecoding candidates at a certain aggregation level, the UE 404 candetermine that the beam pair link 408 has experienced a failure event,and will send a request for beam recovery. The request can either besent back to network node 406 or network node 412 and the new beam pairlink to the network node 306. A new beam pair link 410 between networknode 412 and UE 404 can be formed to retransmit the downlink controlinformation.

The UE 404, network node 406, or mobile network can determine tointroduce another network node (e.g., network node 412) if there are nosuitable antenna pairs on network node 406 and UE 404 to establish a newbeam pair link. This can occur of the object 402 is causing asignificant enough blockage to interfere with the antennas of thenetwork node 406.

Turning now to FIG. 5, illustrated is an example table showingaggregation levels for blind decoding in accordance with various aspectsand embodiments of the subject disclosure

There can be different types 502 of aggregation levels 504, where eachaggregation level 504 has a different size 506 and number of PDCCHcandidate 508. The size 506 is derived by multiplying the number 508 ofPDCCH candidates by the aggregation level 504.

For UE specific search spaces, there can be four aggregation levels, 1,2, 4, and 8, with separate sizes and candidates per aggregation level.Each of the different aggregation levels can have different prioritylists to facilitate the early termination of blind decoding by the UEwhen it receives the transmission from the base station device.

In various embodiments, the aggregation level can be configured by thebase station device or the network for the UE based on a variety offactors, including the link quality of the UE and other quality ofservice concerns. For instance, a UE that is on a cell edge can use anaggregation level that is higher, such as level 8 since the number ofPDCCH candidates are smaller, which can facilitate a lower code rate.

By taking into consideration the aggregation level of the controlresource set, the importance of the beam pair link can be determined inanother way. There are different aggregation levels that a PDCCH has(aggregation level is defined as the number of control channel elementsaggregated for transmission for each PDCCH). There can be 4 possibleaggregation levels (1, 2, 4, or 8). The higher the aggregation level,means the more likely that the UE will decode the DCI, as it occupiesmore CCEs, hence more bits, and uses a more robust coding. So forexample channels that carry system information have a higher aggregationlevel.

Turning now to FIG. 6, illustrated an example block diagram 600 of auser equipment device 602 in accordance with various aspects andembodiments of the subject disclosure.

User equipment device 602 can include a reference signal component 604that receives the reference signal and determines whether the referencesignal quality is below a predetermined threshold, or the signal tonoise ratio is below a threshold. The reference signal component 604 candetermine that a reference signal associated with a beam pair link isbelow a first value determined by a predefined criterion associated witha strength of the reference signal, wherein the beam pair link is atransmission stream between a transmitter antenna and a receiverantenna.

An analysis component 606 can be provided to determine an importance ofthe beam pair link associated with the reference signal. The relativeimportance of the beam pair link can be determined by the analysiscomponent 606 based on the control resource set the beam pair link isassociated with. A control resource set is a set of resource elementswhere each UE attempts to blindly decode the downlink controlinformation. A user can have one or more control resource sets. Eachcontrol resource set can be associated with a search space, and thesearch space can include aggregation level(s) and number of decodingcandidates for each aggregation level.

In an embodiment, user equipment device 602 can be configured withmultiple control resource sets. Each control resource set is associatedwith certain number of blind decoding candidates. (The number of blinddecoding candidates may be implicitly decided by the size of controlresource sets in terms of resource elements A resource element can bethe smallest modulation structure, or data unit. Each control resourceset is associated with a set of beam pair links where each beam pairlink includes a transmitter beam and a receiver beam. Each set of beampair links is associated with a reference signal resource which is usedto estimate the quality of the set of beam pair link.

In an embodiment, a beam failure event can be defined as “more than Neffective blind decoding candidates failed” and the value of N isconfigured by network depending on local conditions. When the referencesignal resource (maybe CSI-RS or SS-block) corresponding to a controlresource set failed, all the blind decoding candidates associated withthe control resource set are also considered to have failed. In someembodiments, a beam failure event can be based on the aggregation levelof the control resource set. For instance, a beam failure event can bedefined as “more than N effective blind decoding candidates with acertain aggregation level that have failed”.

In response to determining that a beam failure event has occurred, theuser equipment device 602 will initiate the beam failure protocol inwhich the recovery component initiates a transmission of a beam recoveryrequest to a base station device associated with the transmitter antennaor another base station device. In response to sending the beam recoveryrequest, the base station can initiate a new beam pair link andretransmit the downlink or uplink control information that was in thefailed transmission.
